刚接屋架内力简化计算方法的有限元验证

VERIFICATION FOR SIMPLIFIED RIGIDLY CONNECTED ROOF TRUSS DESIGN METHOD BY FINITE ELEMENT METHOD

平面桁架常作为承重结构用于工业建筑的屋盖体系中。对屋架内力进行快速有效的计算是设计过程的核心问题之一。应用有限元软件ANSYS对某工程钢屋架的受力情况进行分析,并将其结果与采用简化计算方法得出的结果进行了对比,验证了该方法的可行性。

Plane truss is a major style of sustainahle system for roof. How to design steel roof truss effectively has become one of the critical problems. The ANSYS ,software is used to simulate mechanical state of a practical project. And then the result of ANSYS is compared with the result by the simplified method to verify the practicability of this simplified method.
